4VWX and 5 white hake 1998 stock assessment

By M. Fowler

Abstract

Commercial landings and catch rates, and research vessel survey abundance indices are at or near record lows for the 4VWX/5Zc white hake stock unit. For assessment purposes the stock unit has been partitioned into separate 4V, 4W, and 4X/5 components to reflect discontinuities in white hake distribution. The downward trends in abundance indices and catch rates for 4X/5 suggest that this portion of the stock may be at risk of collapse. Abundance indices of the 4W and 4V components of the stock have remained near record lows since 1995 and 1987 respectively, showing only weak signs of recovery. Current management measures will need to reduce removals significantly to sustain 4VWX/5 white hake.
